Abstract

An electromagnetic relay has a fixed touch piece having a fixed contact, a movable touch piece having a movable contact contactably and separably opposed to the fixed contact, and configured to elastically deform, an auxiliary member configured to energize the movable touch piece to the fixed contact piece side, an electromagnet, and an intermediate member configured to be operated by magnetization of the electromagnet and elastically deform the movable touch piece.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. An electromagnetic relay, comprising:
 a fixed touch piece comprising a fixed contact; 
 a movable touch piece, comprising a movable contact contactably and separably opposed to the fixed contact, and configured to elastically deform; 
 an auxiliary member configured to energize the movable touch piece to the fixed contact piece side; 
 an electromagnet; and 
 an intermediate member configured to be operated by magnetization of the electromagnet and elastically deform the movable touch piece, 
 wherein the auxiliary member comes into surface-contact from a terminal portion of the movable touch piece to a vicinity of the movable contact. 
 
     
     
       2. The electromagnetic relay according to  claim 1 , wherein the auxiliary member energizes the movable touch piece from the surface on the opposite side to the fixed touch piece. 
     
     
       3. The electromagnetic relay according to  claim 1 , wherein the auxiliary member is configured to energize the movable touch piece to the fixed touch piece side up to a predetermined position before closing of the contacts. 
     
     
       4. The electromagnetic relay according to  claim 1 , wherein the auxiliary member is configured so as to no longer energize the movable touch piece after closing of the contacts. 
     
     
       5. The electromagnetic relay according to  claim 2 , wherein the auxiliary member is configured so as to no longer energize the movable touch piece after closing of the contacts. 
     
     
       6. The electromagnetic relay according to  claim 3 , wherein the auxiliary member is configured so as to no longer energize the movable touch piece after closing of the contacts.
